To all whom it may concern:

Be it known that l, ALEXANDER 1. BROWN, a citizen of the United States,and of S racuse, in the county of Onondaga and tate of New York, haveinvented a certain new and useful Motor Agricultural Machine, of whichthe following 1s a specification.

This invention relates to motor agricultural machines and has for itsobject a particularly simple and eflicient arrangement of the engine andthe power transmitting mechanism between the engine shaft and thedriving wheel of the machine, and the movable member or mechanism of theimlement. The invention consists in the cominations and constructionshereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views. 7

Fig. 2 is a detail view of the mower bar and contiguous parts.

Fig. 3 is an elevation, partly broken away, of the driving means andclutch between the engine shaft and the power transmitting mechanismconnected to the tractor wheel.

Fig. 4 is a detail view of the clutch operating means shown in Fig. 3. s

Fig. 6 is an enlarged detail view of said connections, and the means foroperating the clutch thereof.

Fig. 7 is a sectional view taken on the plane of line A-A, Fig. 6.

Figs. 8 and 9, are respectively, a plan and side elevation of theshifting fork for the clutch shown in Fig. 6.

1 designates the frame which may be of any suitable form, size andconstructlon; 2, is the traction or driving wheel which IS, in this formof my invention, located at the rear end of the frame. 3 is a steeringwheel mounted on a fork 4 which in this form of my invention, is shownas carried at the front end of a frame element 5 extending forwardlyfrom the frame 1.

6 designates the agricultural implement,

a resident 15 loosely mounted on connection be Patented July re, real.$45,024:. I

the implement here shown being a mower including a reciprocating knife7.

8 is the engine supported by the frame 1, the engine being usually ofthe internal combustion type although any form of motor may be employed.The crank shaft 9 of the engine is connected to the tractor wheel 2 andto the knife 7 by independently operable and controllable powertransmitting means.

in this embodiment of there is power transmitting one. end of the cranktractor wheel 2 which is controlled by clutch means, and powertransmitting means between the other end of the crank shaft, and theknife 7, the latter being controlled by another clutch means.

he power transmitting means between the rear end of the shaft 9 and thewheel 2' includes a shaft 10 having a pulley l1 thereon connected by abelt 12 to a pulley 13 on the crank shaft, bevel pinions 14 and theshaft 10 and having clutch faces on opposing sides thereof, a clutchsection 16 keyed to the shaft 10 and slidable along the same to connecteither gear 14 or 15 to the shaft, a bevel gear 17 mounted on avertically ex tending shaft 18 journaled in the frame 1 and meshing withthe bevel pinions 14, 15, a gear 19 mounted on the lower end of theshaft 18 and meshing with a gear 20 mounted on a spindle 21 which alsohas a bevel gear ring 22 thereon, and a gear ring 23 on the wheel 2meshing with the gear 22. The clutch 16 is shifted by a suitable meansas a sliding handle 24. When either one of the gears 14 or 15 isclutched to the shaft 10 the power will be transmitted from the crankshaft 9 to the shaft 10 by the pulley 11 through the gear 14 or 15 tothe bevel gear 17, shaft 18 and gears 19, 20, 22 and 23. he gears 14 and15 drive the gear 17 and hence the tractor wheel in opposite directions.

Suitable locking means such as described in my Patent No. 1,247,073,issued November 20, 1917, is provided for holding the wheel 2 frommovement about the shaft 21 and for controlling the swinging of the saidWheel about said shaft, in order to steer the machine but part of mypresent invention, further description thereof is thought to beunnecessary.

my invention, means between shaft 9 and the as this mechanism forms noThe clutch means between the engine shaft and the power transmittingmeans of the tractor includes means for tightening or loosening the belt12 as anidler pulley 25 engaging the belt and carried on the arm 26mounted on a rock shaft 27 having awsecond arm 28 thereon which isconnected to a rock shaft 29 by means of a link 30, the shaft 29 havingan operating lever or pedal thereon.

The power transmitting mechanism between the shaft 9 and the knife 7 ofthe mower is in this embodiment of my invention, connected to one end ofthe engine shaft.

32 is a. shaft section journaled at one end in a hollow section 33connected by a universal joint 34 fastened to the front end of the crankshaft 9, the shaft section 32 being connected at its other end by auniversa joint 35 fastened to a shaft 36 having a crank 37 thereon whichis connected by a link 38 to the knife 7 to reciprocate the same. Themeans for controlling the rotation of the shaft 32 comprises a clutchsection 39 slidable lengthwise of the shaft 32 i into and out ofengagement with the clutch section 40 on the shaft 32.

The mower and the support for the same are movable to differentelevations in the ordinary manner to avoid stones, stumps, and otherobstructions on the ground and to follow the contour of the ground, andare raised by hand as is understood by those skilled in the art. In thislifting and lowering movement the mower moves about a transversehorizontal axis at 41 near the axis of the universal joint 34.

The clutch section 39 is shiftable by means movable about said axis 41and, as here shown, including a yoke 42 pivoted at 43 to the rear endsof links 44 extending on opposite sides of the shaft-32 and carrying attheir front ends a fork 45 coacting with the clutch. This yoke 42 ismounted upon a shaft 46 carried by the frame and is operable by anysuitable means as the lever 49 connected by a link 48 to a rock arm 47on the shaft 46. o

Obviously, upon movement of the lever 49 in one direction or the other,the clutch section 39 will be shifted into or out of engag ement withthe clutch section 40.

he handle 49, pedal 31 and other controlling means for lifting the knifeand also 31 movable member,

the means for steerin the front wheel 3 are all grouped together withinreach of the operator.

This invention is particularly advantageous in that there are direct andindependent driving means between the engine shaft and the tractor wheeland between the the mower knife, or other and in that it provides aparticularly simple, economical and strong construction consisting ofcomparatively few parts. i

What I claim is:

1. In an agricultural machine, the combination of a frame, a drivewheel, an implement including a movable member, a motor having a driveshaft and located with its drive shaft extending lengthwise o-fthe frameand the drive wheel being located to the engine shaft and 1 rear of themotor and the implement near the front end of the frame and in front ofthe motor, and independently operable and controllable powertransmitting means between the rear end of the motor shaft and the drivewheel and between the front end of the motor shaft and the movablemember of the implement, the power transmitting means connected to saidmovable member extending forwardly from the front end of said shaft andbeing arranged end to end therewith, substantially as and for thepurpose described.

2. In an agricultural machine, the combination of an implement movableto different elevations about a substantially horizontal axis, saidimplement including a movable member, an engine, and connections betweenthe engine and the movable member of the implement including shaftsections connected respectively to the engine shaft and to the implementby universal joints, a clutch for connecting the shaft sectionsincluding a' shiftable member slidable lengthwise of one of the shaftsections, and means for shifting the clutch member including a shifterpivoted on a transverse axis near the axis of the universal jointbetween one sha section and the engine shaft, substantially as and forthe purpose s ecified.

In testimony whereo I have hereunto signed my name, at Syra'cuse,'in thecounty of Onondaga, and State of New York, this 5th day of July, 1918.
